San Diego County, San Diego Rat Control Situation:
Hi David, Is a UV blacklight still useful, exterior-wise, if it rains after the rodents leave their urine stains? I am in the process of performing exterior maintenance to better exclude my roof rats. 1) I have a 25 year old cedar shake roof in San Diego California with openings under each shake along the rake edge of the roof at the gable ends of my house. There's no drip edge, i.e. under the shakes I have roofing paper (now somewhat curled) that runs more or less up to and rests right atop the fascia board. Because I have skip sheathing, and since the cross section of a shake is a wedge that is up to one inch at the upper, thick end, this appears to create many huge entry points along the rake edges even though the sheathing is rabbeted into the fascia board. As a result, I'm thinking of getting a UV blacklight to use outside the house to sleuth for urine stains along the upper edge of the gable end shakes and fascia boards. My question is, how easily does the winter rain wash away the urine, rendering this a pointless exercise? 2) I noticed a new product called "rat-out gel" and was thinking of applying it along the rake edges mentioned above. Or, maybe I should just buy many rolls of X-Clude and use that instead. Or maybe both. Any comment? Thanks very much for your website, Doug
My response: First off, I do not have experience using UV lights to detect rat urine. But I do suspect that rain will severely limit the effectiveness of this approach. I have never heard of Rat-Out Gel or XClude, but I typically stick to physical barriers rather than repellent type devices. If your roof makes this impossible, you might have a tough time keeping the rats out.
San Diego Rat Control Tip of The Week
Should I Remove Rats Myself, Or Hire A Pro?
Disposing of rats is something you need to do, however the question is how you can achieve this. You can do this without the help of anybody; however, some would want to employ an expert. So which is the most ideal route to choose?
Let's take a look at the things to consider.
If you are certain that it is only one rat, then there is just one reason to hire an expert unless the rat appears to be sick. If you can't tell if the rat is sick, there are signs to check for and you should get familiar with these. Otherwise, it is just an issue of getting a trap, setting it up, and trusting that the rat will get captured.
There are traps that permit you to kill the rat right away and there are those that will basically trap the rat alive. If you select the ones that kill the rat, when it is dead, just toss it out and your problem is solved. However, if you decide to catch it live, take it to an area where it can't go back into your home and let it go. Ensure you wear gloves when dealing with the rat, regardless of which trap you pick.
If you find that there is more than one rat in your home, then it might be an ideal option to hire an expert. You might not have the necessary skills, time, and expertise to catch multiple rats. Rats are creatures that like to live in huge groups, so you will find that there can be thousands living in one area.
If you notice a spot in your home where they are living, then it is a smart thought to get an expert to come and take care of them. They won't just end the rat infestation in your home, but will likewise dispose of the vermin. This will keep you from having to deal with the problem at all.
